The calculators and guides on Cost of Owning produce estimates for planning purposes only. Actual costs depend on your location, home, contractor, equipment choices, permits and conditions discovered during a job.

• Estimates are not quotes. Always obtain written quotes from licensed, insured professionals.
• Sizing results are rules of thumb and do not replace a professional load calculation or inspection.
• Work involving gas, electricity, refrigerant or structure can be dangerous and may require permits. Hire qualified professionals.
• Savings and payback figures depend on energy prices and usage, which change over time.
